1 Claim.

The present invention appertains to a folder construction for sheet music or the like.

One object of the present invention is to provide a folder construction of the nature referred .5 to herein for protecting sheet music against the usual wear to which it is subjected during use so that the same may be maintained in perfect condition.

A further object of the present invention is the provision of means for supporting and attaching the pages of sheet music within the folder structure in such a manner as to eliminate bending thereof when in use and to thereby facilitate the positioning of the same on a sheet music holder or like structure.

Another object of the present invention resides in the employment of special arrangements for securing the supporting and attaching means on the cover structure of the folder in such a way that when the pages of the sheet music are attached all portions of the pages printed with notes are unobstructed and visible when the folder is opened.

The invention contemplates further certain provisions which permit the attachment and removal of the pages of the sheet music with respect to the folder structure without difficulty and without the possibility of being damaged by such manipulation. Further objects and advantages of the present invention will become more apparent from the following description and drawings in which:

Figure 9 is a section of a portion of the frame member, the section being taken on line 99 of Figure 6.

Figure 10 is a plan view of the cover structure of the folder, the same being taken in an opposite direction as shown in Figure 1.

Figure 11 is a perspective view of the folder construction, certain parts being broken away while others are illustrated in section.

Figure 12 is a perspective view of the folder in closed position.

Referring now to the drawings and especially to Figures 1, 2 and 12, A designates generally the folder construction of the present invention to which the leaves B and C of sheet music have been attached. The folder construction A comprises a cover member 1, bent upon itself at its center 2 as clearly seen from Figure 12 to form a front cover portion 3 and a back cover portion 4. The cover member may be made from manila, pressboard or any other suitable material. The center portion of the cover I is reinforced at 2 by strips 5 of paper, cloth or similar material, which are pasted to both sides of the cover member so that any liklihood of breakage of the cover member at its crease 2 is prevented.

The sides of the cover member are provided with pockets 6 and I adapted to receive the portions of the sides of the sheet music pages in a manner as referred to herein later on.

These pockets are formed from strips of paper, cloth, or equivalent materials which are of a configuration as shown at 3 in Figure 3. Each of these strips is provided with reinforcing members t, preferably made from pressboard, which are secured thereto by pasting the same thereon. The strips 8 comprise further the extensions I0 to facilitate a secure attachment of the strips 8 to the cover member.

The strips 8 are attached to the sides of the cover member by applying mucilage or the like to the surface of the portions i0 and H which are not covered by the reinforcing members 9 and by pasting the extensions l0 and portions I I to the outer side of the cover member in a manner as clearly shown in Figures 5 and 10. During this assembly operation the strips 8 are bent upon themselves at line l2 with the respective side ends of the cover i and the reinforcement member 9 therebetween. The extensions ID are preferably secured to the front side of the cover underneath the portions H, see Figure 10. The reinforcement members 9 lay flat against the end portions of the inner sides of the cover and are not pasted. to the same, so that pockets are formed into which the side end portions of a leaf of sheet music may be inserted as illustrated in Figures 1 and 11.

Attached to the cover member i is a bridge i3 which carries a frame i i, adapted to carry leaf C of the sheet music. The bridge i3 and frame l4 may be separate members secured together in any convenient manner or the bridge may be made as an integral part with at least a portion of the composite structure of the frame.

The side E5 of the frame It and the bridge it are formed from a strip of paper, cloth or the like as indicated at iii in Figure 7, reinforced by pasting thereon strips of pressboard ii and I8. The reinforcing member il forms a part of the bridge structure which also comprises the extension portions 13a and H32). In assembling the bridge with the cover member i, the reinforcing member ii is placed upon the inner side of the rear cover portion directly adjacent the crease 2, while the extension portions E31; and i321 are bent over the upper and lower edge of the cover and pasted to the front side thereof, preferably below the outer strip 5 as will be seen from Figure 10. The attachment of the bridge 53 in the manner referred to above permits the introduction of the front and rear leaves of the sheet music which are in one piece, between the bridge and cover I, so that th side ends of the front and rear leaves generally indicated B can be inserted into the pockets t and i as referred to previously.

The bridge serves also as a support for the portion B of the sheet music especially in view of the rather strong reinforcement member i'i held in close proximity thereto and the cover i.

The portion it, see Figures 6 and 7, of the paper strip it constitutes a hinge about which the frame i4 may be turned like the page of a book.

A paper strip see Figure '7, pasted around the reinforcing member it covers the latter and enhances the appearance of the same.

The side 2| of the frame consists of a reinforcing member 22 covered by a paper strip 23 as best seen in Figure 8.

The upper and lower sides of the frame i i are made from two reinforcing members of pressboard or the like 24 and The member 24 is somewhat smaller than the member 25 and both are held adjacent to each other in ciose proximity by a paper strip 2% bent around the same and pasted thereto as clearly illustrated in Figure 9. The members 24 and 25 in cooperation with strip 26 form pockets 2? and. 23 into which the upper and lower ends of the leaf C are inserted to hoid the latter properly in place on the frame in such a manner that both sides of the leaf C may be viewed upon turning of the frame around the hinge portion is.

The reinforcing members it, and may be an integral part and form a frame structure of pressboard, to which the members 24 at the upper and lower portions of the frame are secured so as to form the pockets 28 and 21 previously referred to, and the various paper strips which cover the pressboard frame structure and mem bers 24 are so arranged that the pockets 25 are closed at their ends 2611..

The cover member I and the various paper or cloth strips covering the various reinforcing members and the pressboard frame structure may be of the same or different colors to enhance the appearance of the finished product.

From the above it will be seen that the outer and inner leaves of sheet music may be easily attached to the cover i and frame l4 respectively and may be readily removed therefrom so that the folder construction may be used over and.

over again.

If desired, a plurality of frame members 14 may be mounted on the bridge 53 to thereby increase the capacity of the folder construction as may be desirable under certain conditions.

The sheet music when attached to the bookiike folder of the present invention is protected against wear and tear and may be retained in perfect condition during long periods of use.

It will be apparent to those skilled in the art, that the cover member may be made of fine leather or calico mounted upon a semi-flexible base and the various strips for covering the reinforcing members, etc., and frame structure may be also made from leather or calico.

In the above it has been mentioned that the reinforcing structure of the frame may be made from separate reinforcing strips i8, 22 and 25. In such case the separate strips may be overlapped at their ends and pasted together or united at their place of juncture in any other convenient manner.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is:

A folder construction for sheet music or the like, comprising, in combination, a cover member having a crease for dividing the same into a rear and front cover portion foldaole upon each other, flat bridge member on said cover member adjacent its crease extending parallel thereto over the inner side of the cover member, means for securing said flat bridge member to the cover member and for holding said bridge member in close relation to the inner side of the cover memher for permitting introduction of a leaf of sheet music between said bridge member and cover, m ans for attaching said leaf of sheet music to the cover member, an open frame structure for carrying another leaf of sheet music with both sides thereof visibly disposed on said frame structure and comprising a flexible part for hingedly attaching said frame structure to said flat bridge member, and means for securing said another leaf to said frame structure.
